VILLAM B. NEVILL, OF ROOKVVALL, TEXAS, ASSIGNOR OF ONE-HALF TO E. W. HARDIN, OF SAME PLACE.

ANTIREFILLING BOTTLE.

SPECIFICATION forming part of Letters Patent N 0. 574,442, dated January 5, 1897. Application filed May 13, 1896. Serial No- 591,4l5. (No model.)

To all whom it may concern.

Be it known that I, WILLAM B. NEVILL, a citizen of the United States, residing at Rockwall, in the county of Rockwall and State of Texas, have invented a new and useful Antirefilling Bottle, of which the following is a specification.

The invention relates to improvements in antirefilling bottles.

The object of the present invention is to improve the construction of antirefilling bottles and to provide a simple, inexpensive, and efficient one, which may be readily sealed after it has received its original contents, and which, in order to obtain access to its 0011- tents, will have to be suff ciently mutilated to prevent it from ever afterward being used in trade, thereby effectually preventing the adulteration of the contents of a bottle or the refilling of the same with an imitation of its original contents.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure 1 is a perspective view of a portion of a bottle constructed in accordance with this invention. Fig. 2 is a central vertical sectional view. Fig. 3' is a horizontal sectional view. Fig. 4 is a detail perspective view of the outer stopper or plug.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a bottle provided on the interior of its neck 2 with an annular groove 3, located intermediate of the ends of the neck and adapted to be automatically engaged by an elastic locking-ring 4 of a stopper or plug 5, which is received within the upper portion of the neck. After the bottle has received its original contents a cork 6 is inserted in the neck and is arranged in the lower portion thereof below the annular groove 3, and the top of the cork is slightly hollowed out or concaved to receive the lower end 7 of the stopper 5.

The stopper 5,which is preferably constructed of glass, has its lower end 7 tapered, and it is provided above the tapered portion with an annular groove 8, receiving the elastic compressible locking-ring 4, which is adapted to be compressed when the stopper is forced into the upper portion of the neck of the bottle and which is capable of expanding and automatically engaging the interior groove 4 of the neck of the bottle, whereby the stopper is locked therein. The grooves 3 and 8 have horizontal upper and lower walls or shoulders, and the elastic washer is partially seated in both of them when the stopper is in position. It effectually prevents the withdrawal of the stopper, and in order to obtain access to the cork and the contents of the bottle the upper portion of the neck of the bottle has to be broken off. This is accomplished by a light blow, as the interior groove 3 of the neck of the bottle reduces the neck in thickness at the elastic ring and forms a frangible connecting 7o ligament. The cork, by being arranged below the connecting frangible ligament, prevents any chips or pieces of glass from entering the bottle.

After the upper portion of the neck is broken off the cork may be readily drawn, and the breakage of the upper portion so mutilates the bottle that the latter is prevented from ever afterward beingused in trade, thereby avoiding adulteration of the original contents of the bottle or a future sale of the bottle with an imitation of its original contents.

It will be seen that the antirefilling bottle is simple and comparatively inexpensive in construction, that it is positive and reliable in operation, and that after it has received its original contents it cannot be refilled and again used in trade. It will also be apparent that the original contents of a bottle cannot be diluted or adulterated without mutilating 0 the bottle to such an extent as to prevent the sale of the same.

Changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

What I claim is The combination of a bottle provided on the interior of its neck with an annular groove reducing the neck in thickness at that point,

and forming a frangible ligament, a cork arand the groove of the stopper or plug, subranged in the neck below the groove and havstantially and for the purpose described.

ing its upper face concave or hollowed out, In testimony that I claim the foregoing as a stopper or plug having a tapered lower end my own I have hereto afiixed my signature in 5 to fit the hollowed-out portion of the cork, the preseneeof two Witnesses.
